I have three monitors. The two first I use as regular independent screens, then on a third screen, which is a large widescreen monitor, I want to take the source of the two first displays and output it to a combined split-screen view (so that to screens are side by side in the third monitor).
Primarily, is this possible without buying separate hardware or can it be done software-wise from a graphics-card?
I plan to to buy a Matrox M9138, which has advanced multi-monitor features.
If need additional hardware to to this, what are they called and where do I buy it?
